Abstract

The invention relates to a constant rotating speed device which comprises a shell, an input gear pair, a planetary transmission mechanism and a ratchet mechanism, wherein a driven gear of the input gear pair is fixedly connected with a solar gear of the planetary transmission mechanism and engaged with a driving gear of the input gear pair, the ratchet mechanism is fixedly mounted on a shaft which is integrated with the driving gear, a pawl of the ratchet mechanism is embedded on a ratchet-type inner gear, the planetary gear rack is connected with an engine, a gear ring is connected with a generator, and the shaft is connected with an air turbine. According to the use requirements of the generator, the invention realizes the conversion of the single input and the single output of the mechanism by the one-way rotation characteristic of the ratchet structure, can surely limit the rotating speed of the generator within a constant value regardless of the rotating speed of the engine, guarantee the use requirements of the generator and have favorable effect after use verification.

Description

The constant speed rotational speed devices
Technical field
The present invention relates to a kind of constant speed rotational speed devices.
Background technology
In existing mechanical equipment, the alternating current generator that has requires input speed to be no more than steady state value, and then guarantees the stable of power generation performance.And the rotating speed of the engine that is connected with generator is constantly improving, and therefore when the rotating speed of generator surpasses steady state value, needs a constant speed drive device this moment, is no more than steady state value with the rotating speed that guarantees generator.
Summary of the invention
The transmission device that the purpose of this invention is to provide a kind of generator constant speed guarantees that the rotating speed of generator is no more than steady state value.
Technical scheme of the present invention is: device comprises housing, input gear pair, epicyclic transmission mechanism, ratchet mechanism composition, described epicyclic transmission mechanism comprises central gear and the planetary gear that with pinion frame be fixed together intermeshing with it, and the planetary gear outside is engaged with gear ring; The driven gear of described input gear pair and the central gear of epicyclic transmission mechanism are affixed, the driving gear of input gear pair and driven gear engagement, go up the ratchet matrix that fixedly mounts ratchet mechanism with the axle of driving gear one, also be provided with on the described ratchet mechanism by rotating shaft and be installed in ratchet matrix ratchet, on the housing of device the ratchet-type internal gear is housed, described ratchet is embedded on the ratchet-type internal gear by elastomeric element; Described pinion frame is connected with engine, and gear ring is connected with generator, and described axle is connected with air turbine.It is little than the quality of the other end that described ratchet is embedded in ratchet-type internal gear one end, and described ratchet also can be 3.
When engine rotation, drive planetary gear by planet carrier and rotate around central gear, by the effect of ratchet, central gear does not rotate, and planetary gear drives gear ring and rotates, generator for electricity generation; When the rotating speed of generator surpasses constant rotational speed, under the effect by transducer, start turbine rotor, because the direction that turbine rotor rotates is the opposite direction that ratchet blocks direction, therefore can drive axle and be rotated, thereby drive the central gear rotation, direction of rotation is that the pinion frame direction of rotation is opposite, therefore can guarantee that the rotating speed of gear ring is constant, and then make the invariablenes turning speed of generator.It is little than the quality of the other end that ratchet is embedded in ratchet-type internal gear one end, therefore mass centre is in the ratchet rear end, when turbine rotor rotates, be subjected to receive in the centrifugal action ratchet during ratchet work, ratchet is thrown off from the ratchet-type internal gear fully, thereby friction is reduced or disappearance, raise the efficiency, reduce wearing and tearing, increased useful life.Use three pawl structures, not only satisfy the instructions for use in space, can also guarantee the embedding effect of ratchet, improve to use and go all out to do one's duty regardless of personal danger.
The present invention is according to the instructions for use of generator, characteristics by the unidirectional running of ratchet structure, realized the conversion of single input of mechanism and dual input, no matter muchly guaranteed in engine speed, can both make and make the rotating speed of generator be no more than steady state value in the transmission process, ensured the instructions for use of generator, through using checking, respond well.
